Yet, this has the printing machine of runner roller, carry out the occasion of the continuous printing of pattern little as seal etc. at printing to long ribbon shape, as on the full week of runner roller, not arranging forme, the part that do not stamp will be on printing periodically occurs, cause the waste of printing.For this reason, if on the full week of runner roller, arrange forme, time-consuming more with making in the making of forme.And, when the little pattern of equidistant continuously printing etc.,, perhaps form tabular forme if not form forme cylindraceous, then twist on the week of runner roller, thereby make the cycle unanimity of pattern etc., still can not carry out equally spaced printing.Thereby the making of this galley needs masterful technique, and this will bring the raising of cost.

The Japan Patent spy opens clear 58-98255 and has introduced the printing machine that comprises the forme roller that has forme on it that a kind of energy adaptation is printed continuously to the long ribbon shape printing, the black mechanism that is coated with of this printing machine at first takes out China ink from black groove with inking roller by normal the employing, further China ink is reached the left side of close above-mentioned forme roller then by a series of running roller groups, on the right ink roller, by two swing ink transfer mechanisms China ink is reached respectively again and carry out required printing on this forme roller, but also there is the uniform inadequately problem of the China ink that is coated on the forme roller in so black mechanism that is coated with, and this mainly is owing to be coated in an above-mentioned left side near forme roller, black uneven cause on the right ink roller.

Therefore, the present invention is in view of the above problems, simultaneously seek to reduce the cost of forme when on the printing of long ribbon shape, printing little pattern continuously, also want to obtain good printing state, and when seeking to construct summary, the printing ink homogenising that also will seek to obtain adding up creates as purpose.

The present invention, becoming by the activity box support that will be positioned at forme roll shaft both ends can be on the guide rail of a pair of level back and forth, meanwhile, the gear that will have with the pitch circle of the equal diameters of this forme roller is fixed on the forme roller, at horizontal guide rail on one side, longitudinal direction configuration tooth bar along gear, make with aforesaid gears and be meshed, the direction that intersects vertically at the vibration-direction with forme roller disposes printing, interrelate down in reciprocating motion to form this printing with forme roller, off and on by printing position by the forme roller decision, be coated with roller and configuration is coated with China ink in multiple stroke the roller that is coated with in forme roller configuration in the stroke to what its galley was coated with China ink, making these be coated with roller respectively contacts with these rotating each ink rollers of gyratory directions rightabout separately that are coated with roller with the edge, meanwhile, by contacting and a plurality of rider rollers of interlock with the running roller that comes from ink tank successively, form continuously respectively printing ink applying mechanism to these inking roller ink supply, this printing ink applying mechanism also forms the rider roller wheel of an end among a series of rider roller groups that make successively contact and interlock and contacts from the inking roller that ink tank is sent printing ink, the running roller of these a series of rider roller groups' the other end as distribution rollers, this distribution rollers directly or by the running roller below two and aforementioned each ink roller is contacted, also can adjust running roller equably the above-mentioned ink roller that is coated with is directly contacted, thereby can solve the above problems by two printing ink are set.

Accompanying drawing is expression one embodiment of the invention, and Fig. 1 is the concise and to the point front view of its critical piece, and Fig. 2 is the profile along II among Fig. 1-II line.

Below, one side is with reference to accompanying drawing, and one faces one embodiment of the invention describes.

Symbol shown in the figure 1 is a forme roller, and as shown in Figure 2, its crossbearer becomes the activity box 3,3 with respect to its two ends of 2 freely to turn round.

This a pair of activity box 3,3 by backing roll 4, is supported to and can moves back and forth on the horizontal guide rail 5 of framework.

In addition, in the both ends or one end of aforementioned axis 2 (being illustrated as two ends), fixedly has gear 6,6 with the pitch diameter of forme roller 1 equal diameters, on the other hand, on horizontal guide rail 5, vertically be separately installed with tooth bar 7,7 along it, gear 6,6 and this tooth bar 7,7 are meshing with each other.

Next, as shown in Figure 1, the both ends of chain-drive mechanism 8 are fixed on the aforesaid activity box 3, these chain-drive mechanism 8 covers hang on a plurality of directive wheels 9 and the driving wheel 10.The gear 11 that makes sector gear 12 and form on the axle of this driving wheel 10 is meshed, and drives driving wheel 10 by sector gear 12 is shaken.In addition, about replacing chain-drive mechanism 8, also need not many speeches with power-transmitting parts such as bands.

This sector gear 12, link to each other with driven gear 13 with rocking bar 14, and then the former moving gear 16 on driven gear 13 and the motor reel 15 is meshed, by making motor reel 15 revolutions, by former moving gear 16, driven gear 13 and rocking bar 14, sector gear 12 is shaken.

In addition, in the middle part of horizontal guide rail 5, with fixed guide plate 17 on the following mutually contour position of forme roller 1.At this place, printing position above guide plate 17 by forme roller 1 decision, on the direction that the vibration-direction with forme roller 1 intersects vertically, putting the printing 18 of long ribbon shape, with pressure roller 19 and driven roller 20 this printing 18 is being seized on both sides by the arms, and will by with the intermittent-rotation of the synchronous driven roller 20 of the reciprocating motion of forme roller 1, it is moved off and on, be exactly in addition on the part of the periphery of forme roller 1, forme 21 is fixed along circular arc.

On the one hand, thereby with this forme roller 1 contact be coated with China ink be coated with roller by when forme roller 1 in stroke when the counter clockwise rotation direction is turned round, contact and the clockwise rotating roller 22 that is coated with of gyratory directions in edge with forme 21, with when forme roller 1 in multiple stroke during along gyratory directions revolution clockwise, contact with forme 21 and form along the rotating roller 23 that is coated with of counter clockwise rotation direction.This two is coated with roller 22,23 and shakes upward, contacts with different ink roller 24,25 respectively, thereby rolls China ink.

On the other hand, by black liquid 27, the China ink in the black groove 26 to the outside, is just supplied with to ink roller 24,25.This inking roller 27 and rider roller 28 dispose in contact, and this rider roller 28 also will dispose in contact with a rider roller 29.And this rider roller 29, adjust roller 30 by contact, to contact configuration with distribution rollers 31, and this distribution rollers 31, adjust roller 32 by contact, a formation and a side's ink roller 24 contacts, meanwhile, also will adjust roller 34 with contacting by gyratory directions conversion roller 33, formation and another ink roller 25 contact.Just, as rider roller, except rider roller 28 and rider roller 29, the effect that roller 30 and distribution rollers 31 play rider roller is too adjusted in contact, and with this rider roller 28, rider roller 29, roller 30 is adjusted in contact, distribution rollers 31 forms a series of rider roller groups, make as the rider roller 28 of the running roller of one end and inking roller 27 contact and the running roller of its other end as distribution rollers 31, make these rider rollers group contact linkage successively.In addition, it is isolated in this occasion rider roller 28 might to be formed from inking roller 27 and rider roller 29, makes it to stop at any time from black groove 26 ink supply.

Will form one in addition and make an aforesaid ink roller 24 and another ink roller 25, be not to adjust roller 32 etc. but by other contact two make the adjustment roller 35 of printing ink homogenising and the direct printing ink applying mechanisms of contact by aforementioned rider roller 28,29 and contact.Because even the formation of this mechanism is by aforesaid each running roller 28,29,30,31,32,33 and 34 combination, make ink roller 24 and ink roller 25 be in revolution in the other direction, adjust roller 35 by the printing ink homogenising, ink roller 24 and 25 is contacted, in addition with having no obstacle each other, adjust added on the roller 34 black inhomogeneous even adjust roller 32 with contacting, adjust roller 35 by this black homogenising the China ink that adds is become evenly in contact.

In addition, 36 is to be used for contacting the adjustment guider of adjusting roller 30, contact adjustment roller 32, gyratory directions conversion roller 33 and contacting the position adjustment of adjusting roller 34 among the figure, and thick arrow is represented the flow direction of printing ink, and thin arrow is represented the gyratory directions of aforementioned each running roller.Be exactly in addition between distribution rollers 31 and ink roller 24 and ink roller 25, need not adjust roller 32 by contact and adjust roller 34 with contacting, distribution rollers 31 is directly contacted with ink roller 24, also can between distribution rollers 31 and ink roller 25, only make its contact by gyratory directions conversion roller 33.In addition, as previously mentioned, if can form rider roller 28 and inking roller 27 and rider roller 29 are isolated, so just can be easy in time perhaps to stop ink supply to ink roller 24,25 ink supply.

Next, the action to relevant printing machine of the present invention describes.

When motor reel 15 revolutions, former moving gear 16 just makes the driven gear 13 that is meshed with it turn round with certain speed reducing ratio.Driven gear 13 becomes gyration to shake by rocking bar 14 passes to sector gear 12, and sector gear 12 is transformed into its swing movement the gyration of the both forward and reverse directions of gear 11.By chain-drive mechanism 8 activity box 3 is passed in the gyration of both forward and reverse directions with gear 11 coaxial driving wheels 10, this activity box 3 is moved back and forth along horizontal guide rail.A pair of activity box 3, the rolling pair by support roller 4 are done slight moving, and axle 2 are accompanied by move back and forth and do parallel moving.Because of the parallel of activity box 3 moves back and forth.It is mobile that gear 6 and tooth bar 7 are being meshed, and forme roller 1 and axle 2 move back and forth repeatedly doing the rotating while with the peripheral speed identical with the translational speed of activity box 3, just make counter-clockwise direction to turn round when left lateral, turn round along clockwise direction during right lateral.

So the reciprocating motion of forme roller 1 is specified to and will carries out with interrelating intermittently of the swing movement of the above-below direction that is coated with roller 22,23 that moves and printing 18 to move synchronously with forme roller 1.

That is, be positioned at the occasion on right side, be coated with roller 22 and shake and descend and rotate and contact with the circumference of forme roller 1 at forme roller 1.In addition, when being coated with that roller 22 periphery with forme roller 1 is separated and when shaking upward, be coated with roller 22 and ink roller 24 contacts, this ink roller 24 is adjusted roller 30 by rider roller 28,29 or contact, and distribution rollers 31 grades are turned round when forming uniform printing ink face.Therefore and the ink roller 24 contacted rollers 22 that are coated with, contact, China ink is coated in the part of the periphery of forme roller 1, promptly on the face of forme 21 by shaking downwards and rotating with the periphery of forme roller 1.At this moment, forme roller 1 one left side of face move and turn round, and one side is rotated to contact and is coated with China ink by being coated with roller 22 and forme roller 1.

On the other hand, when forme roller 1 was mobile to the left, forme roller 1 turned round with the peripheral speed identical with translational speed, rotated with the printing 18 that is temporarily stopping at middle position to contact, and printed under certain barrel pressure.Then, when forme roller 1 moved to the left side, printing 18 was driven by pressure roller 19 and driven roller 20, and only mobile certain-length stops again, the width that this length is equivalent to print.Next, when forme roller 1 is mobile to the right,, be coated with China ink to forme 21 with being coated with roller 23 with aforementioned the same.By carrying out these operations repeatedly, little pattern is printed onto successively with certain interval on the printing 18 of long ribbon shape, in addition, the printing ink applying mechanism of this moment at first takes out China ink with inking roller 27 from black groove 16.

And then make printing ink adjust roller 30 by rider roller 28,29 and contact from inking roller 27, move to distribution rollers 31 more successively.By distributing with distribution rollers 31, two ink rollers 24 about being sent to, 25 printing ink that get on, just with respectively being coated with roller 22,23 formes 21 to forme roller 1 apply, yet meanwhile, also will accomplish the following circulation of printing ink energy, promptly adopt the printing ink homogenising adjust roller 35 with China ink from ink roller 24 to ink roller 25, and transport to ink roller 24 from ink roller 25.Thereby,, on ink roller 24,25, also can coat printing ink equably even a series of rider roller group is arranged.In addition, different with the aforementioned printing ink that send, make each running roller revolution, and to the detergent remover of running roller surface injection as organic solvent, with scraping removal ink at a place, because each running roller is made to the circulatory system as the thing of scraper plate, so the printing ink on all running rollers all can be removed, and makes cleaning also very convenient.

By above-mentioned the present invention who forms, the activity box 3 at the both ends of the axle 2 that is positioned at forme roller 1 can supported on horizontal guide rail 5 reciprocatingly, meanwhile, the gear 6 that will have with the pitch circle of the equal diameters of this forme roller 1 is fixed on the forme roller 1, one side at horizontal guide rail 5, longitudinal direction configuration tooth bar 7 along gear 6, make it to be meshed with said gear 6, the direction configuration printing 18 that is becoming to intersect vertically with the vibration-direction of forme roller 1, because this printing 18 interrelates with the reciprocating motion of forme roller 1, and intermittently by printing position by forme roller 1 decision, also just doing simultaneously or revolution in the other direction so forme roller 1 one side is reciprocating, no matter be toward stroke, multiple stroke can both print on printing 18, and, because this moment, printing 18 was that reciprocating motion with forme roller 1 interrelates, and pass through the printing position off and in the direction that intersects vertically with this reciprocating motion, therefore there is no need forme 21 is installed on the full side face of forme roller 1, as long as with the forme 21 of bending just on the part of forme roller 1, install can, thereby make the making of forme 21 easy.In addition,, make the added printing ink of paper all rightly, can obtain and the equal effect of runner printing because forme roller 1 is with rolling pair (roll contact) intermittently mobile printing 18 to be printed.In addition, the printing 18 for long ribbon shape will cut off after the printing, because printing 18 is intermittently to move, thereby as long as rely on cutting knife to move up and down, just can correctly and expeditiously cut off operation.

And, owing to form a following printing ink applying mechanism, promptly disposed forme roller 1 in stroke, be coated with the ink roller 22 of China ink and in multiple stroke, be coated with black ink roller 23 to its forme 21, make along being coated with roller 22 therewith, rotating each ink roller 24 of the direction that 23 gyratory directions is opposite separately, 25 are coated with roller 22,23 with these contacts, meanwhile, by contact a plurality of rider rollers of linkage successively through black groove 26, be the rider roller group, continuously printing ink supplied with these ink rollers 24,25 respectively, thereby, carry out ink supply to the forme 21 of forme roller 1 respectively continuously by contact the rider roller group energy of linkage successively through black groove 26.

In addition, because being coated with the following form of black mechanism, that is: make interlock a series of rider roller group an end rider roller 28 and through black groove 26 send the China ink inking roller 27 contact, with the running roller of this a series of rider roller groups' the other end as distribution rollers 31, make this distribution rollers 31 directly or by the running roller below two, respectively with aforesaid ink roller 24,25 contacts, and ink roller 24 and ink roller are turned round for 25 one-tenth in the other direction, and should this ink roller 24 directly be contacted with ink roller 25 by two running rollers, thus a series of rider roller group can be passed through, and, finally series is divided into two with distribution rollers 31, directly or only just can be through ink tank 26 by the running roller below two, continuously to ink roller 24 ink supply, so the number that can make running roller is seldom, mechanism itself obtains simplifying, and reaches the purpose of miniaturization.

In addition, owing to be to allow two running rollers and distribution rollers 31 contact, so rolling from distribution rollers 31 when getting printing ink, get China ink by a running roller at first, then get China ink by another running roller, so the China ink that the running roller of getting China ink is at first coated is many, getting the China ink that the running roller of China ink coats after making tails off, it is black inhomogeneous that thereby generation ink roller 24 and ink roller 25 are coated, if adopt by two running rollers, ink roller 24 directly contacted with ink roller 25, then owing to can make from being coated with the many directions of China ink with these two running rollers and to be coated with a black few side printing ink is moved, average to reach printing ink, the result has eliminated ink roller 24 and ink roller 25 is coated with the inhomogeneous of China ink, and the generation printing is inhomogeneous never again.In addition, owing to, can clean printing ink more conveniently, therefore, can finish with the very short time when changing in the operation by each running roller 24,25,28,29,30,31,32,33,34,35 counter-rotating.

As described above, as adopt the present invention, then can obtain following various good fruit, promptly compare with the printing machine that had the runner roller originally, can be when the forme cost of manufacture reduces, its structure is simplified, can also eliminate on each ink roller to be coated with China ink inhomogeneous and reach the purpose of miniaturization, and the cleaning of each running roller is carried out easily, and can provide a kind of both cheap, and not have the printing machine that prints uneven problem fully.
